2 Claims. (Cl. 121) UNITED STATES PATENT OFFICE.

This invention relates to a conveyer upon which footwear may be assembled.

Heretofore in the construction of footwear it has been usual to employ a. trained operator who performed all the operations in the assembling of the article. Such an operator necessarily had to be highly skilled in the art, which necessitated a long training period and resulted in a highly paid operator which increased the cost of building footwear.

It is an object of this invention to provide a device whereby the operations of building footwear maybe separated so that the individual workmen need not be skilled in as many opera- 5 tions, with the result that their training period may be short and the cost of production correspondingly lower.

Another object of the invention is to provide a machine whereby footwear may be built in steps,

thus requiring less handling of the materials which go to make up the article footwear and which reduces the necessary handling of the form upon which the article is built.

Other objects of my invention will become 5 obvious in the detailed description which follows,

' reference being had to the accompanying drawings, in which:

Fig. 1 is a side elevation of one end of my ma.- chine; I

Fig. 2 is an end elevation partly in section of my machine; 1

Fig. 3 is a detailed view of the truck of my machine;

Fig. 4 is a detailed view showing a modification 5 of the article support.

In the manufacture of an article of footwear, I

as carried out on my machine, the article 1 is built upon the last or form 2 which is supported on the plate 3 and the end of which abuts against the dowel block 4. Plate 3 and dowel block 4 are rotatably mounted by

pins

5 and 6 respectively in thearms of the bifurcated article support 7,

which article support is provided with a plate 8 rotatably mounted by means of pin 9 on the bearing face of the bracket 10, which is integrally or otherwise connected with the truck 11.

The truck 11 has mounted thereon rods 12 held in position by the screws 1313. Rollers 14 are positioned between the upper and lower ends of 60 each rod 12 and the portions of the truck 11 to which the rod is connected, said rollers being rotatable about the screws 13. An arm 15 extends from the rod 12 and carries rotatably a flanged roller 16. A flanged roller 17 is rotatably mounted on a boss formed on the lower end of the rod 12.

The rollers 14--14, 16 and 1'7 engage

tracks

18 and 19, as shown in Fig. 1. The roller 16 and corresponding roller 14 engage opposite sides of the track 18 to prevent lateral movement of the truck with respect to the track, a flange of the roller 16 serving to limit the upward movement of the truck. The roller 17 and the corresponding roller 14 engage the track 19, the roller 1'7 serving to carry the weight of the truck, and the flange of the roller 1'7 and the roller 14 together serve to prevent lateral movement of the truck with respect to the track.

The

tracks

18 and 19 are united in a frame by means of the beams 20 which support the tracks onthe upright frame 21. Upon the upper track 18 and the upper beam 20 is supported the table 23 upon which the materials to be used in constructing the article of footwear may be conveniently placed, as well as the tools employed by the workmen.

One of the rods 12 of the carriage 11 has an extending arm 25 which is connected by means of the links 26 to the chain 27. The chain 27 is trained over sprockets '28 rotatably mounted at opposite ends of the machine. so

One of the sprockets 28 is keyed to the shaft 29 which is rotatably mounted in suitable bearings carried in the frame of the machine and which has keyed thereto the worm wheel 30 engaged by the worm 31. Worm 31 is keyed to shaft 32 which rigidly carries the sprocket 33 driven by means of chain 34 from the sprocket 35 of the speed reducing mechanism 36. Power is trans-'- mitted to the mechanism 36 by means of the shaft 37 clutched to the shaft 38 leading to a suitable source of power.

In the operation of the machine the source of power acting through the speed reducing and motion transmitting mechanism drives the chain thereby moving the carriage 11 along the

tracks

18 and 19 so as to carry the form or last 2 from operator to operator, each of whom applies certain elements of the article of footwear as it passes by so that when the last has completed the circuit of the table, the article of footwear has been completed.

In Fig. 4 is shown a modification of the article supporting device in which a. bracket 10 rotatably carries the support '71 which has rotatably mounted thereon, as at '72, the plate '73. The plate '73 1 carries the dowel block 74 upon which the form or last may be mounted and the plate '73 is provided with apertures 75 to beengaged by the detent 76 so as to hold the plate '73 in adjusted position. v

While certain modifications of my invention have been described in detail as examples of my invention, it is not intended to limit my invention thereto inasmuch as many variations in the details of the machine may be made all within the scope of my invention, which is indicated by the following claims.

Having thus described my invention, what I claim and desire to protect by Letters Patent is:

1. A conveyer for making footwear having in combination a table, a frame for supporting said table, tracks forming a part of the frame, a truck mounted in movable engagement with said tracks, means for imparting movement to said truck, and an article support mounted on the truck, said article support having a rotatably mounted plate for supporting the shank of a boot tree and a 1'0- tatably mounted dowel block for engagement with the shank end of the boot tree.

2. A conveyer for making footwear having in combination a table, a frame for supporting said table, tracks forming a part of the frame, a truck mounted in movable engagement with said tracks, means for imparting movement to said truck, and an article support mounted on the truck, said article support being adjustable with respect to the truck and having a rotatably mounted plate for supporting the shank of a boot tree and a rotatably mounted dowel for engagement with the shank end of theboot tree.
